(TU Delft Hydraulic Structures and Flood Risk; Deltares) Contributor Lang, M. (editor) Klijn, F. (editor) Samuels, P. (editor) Date 2016 Abstract The Dutch design codes for the dikes with retaining walls rely on Finite Element Analysis (FEM) in combination with partial safety factors. However, this can lead to conservative designs. For this reason, in this study, a reliability analysis is carried out with FEM calculations aiming to demonstrate the feasibility of reliability analysis for a dike with an anchored sheet pile wall modelled in the 2D FEM, Plaxis. Sensitivity and reliability analyses were carried out and enabled by coupling the uncertainty package, OpenTURNS and Plaxis. The most relevant (ultimate) limit states concern the anchor, the sheet pile wall, the soil body failure (global instability) and finally the system. The case was used to investigate the applicability of the First Order Reliability Method (FORM) and Directional Sampling (DS) to analysing these limit states. The final goal is to estimate the probability of failure and identify the most important soil properties that affect the behaviour of each component and the system as a whole. The results of this research can be used to assess and optimize the current design procedure for dikes with retaining walls.
